Subject: [PATCH 5/8] connect: split ssh option computation to its own function
Date: Mon, 20 Nov 2017 13:26:19 -0800 [thread overview]
Message-ID: <20171120212619.nqtijn5ygypixmw6@aiede.mtv.corp.google.com> (raw)
In-Reply-To: <20171120212134.lh2l4drdzu6fh5g2@aiede.mtv.corp.google.com>
This puts the determination of options to pass to each ssh variant
(see ssh.variant in git-config(1)) in one place.
A follow-up patch will use this in an initial dry run to detect which
variant to use when the ssh command is ambiguous.
No functional change intended yet.
Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

Split out to make patch 6 easier to read, as suggested at
https://public-inbox.org/git/xmqq60b59toe.fsf@gitster.mtv.corp.google.com/.
Added a function comment to make the purpose and API of this internal
helper clearer.
